The current patrol detector has the advantages of portability, accurate test, economy and practicality. The utility model is a tool for detecting the working condition of the oil sucking pumping well in the oil field production.
Description
The utility model belongs to the rod-pumped well testing tool in the field production management, when relating in particular to the motor load variation, and the time dependent dynamic current patrol instrument of current of electric.
At present, the current detecting instrument, the power instrument that in scene, China oil field, use, though also can finish the task of diagnostic analysis rod-pumped well operating mode, because also there are some defectives like this in the components and parts of selecting and the limitation of structural design: complex structure, carry and inconvenient operation; Operating personnel's technical quality is required high; Sense cycle is long, can not in time find the fault well; The manufacturing cost height is unfavorable in oil field basic unit widespread usage etc.
The purpose of this utility model is the deficiency at existing testing tool, and a kind of usability height, test is accurate, easy to carry, with low cost and detection speed is fast electric current logging are provided.
The technical solution of the utility model is: electric current logging of the present utility model: comprise portable cabinet, keyboard, current sensor, power supply, signal input interface, signal output interface, charging inlet and main frame.Signal input interface can be on-the-spot current signal interface or current sensor signal interface, and signal output interface is communication interface or display interface device; Host A. comprising: wiring board, current sensor, signal processing circuit, analog to digital converter, microprocessor, program storage and data-carrier store; Current sensor directly links to each other with analog to digital converter at motor phase line up-sampling and through signal processing circuit, and analog to digital converter links to each other with microprocessor; Or B. comprises wiring board, signal processing circuit, analog to digital converter, microprocessor, program storage and data-carrier store; Signal input interface links to each other with the signal processing circuit of main frame, links to each other with microprocessor through analog to digital converter again.
In above-mentioned several modes, because apparatus structure is reasonable in design, the each several part circuit adopts general integrated component, the testing process sequencing, make the electric current logging be more convenient for carrying, simple to operate, detection time short, is convenient to patrolling and examining rod-pumped well.
In addition, above-mentioned signal output interface can be communication interface or display interface device, because the data of gathering can and be transmitted outside instrument in instrument stored, demonstration, makes this instrument go for the multiple needs at scene, oil field.
Owing to taked above technical scheme, made the characteristics that the utility model has possessed the usability height, test is accurate, easy to carry, cost is low and detection time is short.
Below, with specific embodiment the utility model is further specified in conjunction with the accompanying drawings:
